Licenses, etc.

Hello friends, I am a new user, and I purchased a solo license, from there I installed the license on a virtual machine, and got a little tangled up, and every time I deleted the machine completely, now I can not install the license and I get the following message: "The cPanel license server replied that the license has been activated on too many machines (600). Please contact billing@cpanel.net The exact message was: The license has been activated too many times on different machines" I would be happy to help, I have no patience to wait for support Thanks in advance for the answers
